Time-dependent Nonlinear Optical Susceptibility of an Out-of-Equilibrium Soft Material
Neda Ghofraniha, Claudio Conti, Giancarlo Ruocco +1
We investigate the time-dependent nonlinear optical absorption of a clay dispersion (Laponite) in organic dye (Rhodamine B) water solution displaying liquid-arrested state transiti…
Aging of the Nonlinear Optical Susceptibility of colloidal solutions
Neda Ghofraniha, Claudio Conti, Giancarlo Ruocco
Using Z-scan and dynamic light scattering measurements we investigate the nonlinear optics response of a colloidal solution undergoing dynamics slowing down with age. We study the…
Laser beam filamentation in fractal aggregates
Claudio Conti, Neda Ghofraniha, Giancarlo Ruocco +1
We investigate filamentation of a cw laser beam in soft matter such as colloidal suspensions and fractal gels. The process, driven by electrostriction, is strongly affected by mate…
